The last Canadian pennies have already been minted, and those still in distribution will, little by little, be taken out of circulation as they cycle through our banks. Myself, I have large coffee cans full of pennies that I will probably roll eventually and turn in at the bank. But this morning, I saw a new use for these coins on a gardening show: they can be used as a slug deterrent!
This may not be news to many of you, but it’s a very simple solution to a really ugly problem. I’m certainly going to give it a try. Apparently, if you place copper pennies around plants where slugs are actively feeding, those that touch the copper coins will receive a mild shock, (when the copper and their “slime” mix) discouraging them from entering the area.
Brilliant!
